这是我的脚本，用于获取纬度，经度和地名。我只能得到纬度而不是地名。
<script type="text/javascript">
$(document).ready(function () {
var longitude = $('#longitude');
var latitude = $('#latitude');
var hiddenControl = '<%= inpHide.ClientID %>';
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function (p) {
longitude.text(p.coords.longitude);
latitude.text(p.coords.latitude);
document.getElementById(hiddenControl).value = p.coords.latitude + "," + p.coords.longitude;
var LatLng = new google.maps.LatLng(p.coords.latitude, p.coords.longitude);
// alert(p.coords.latitude);
var mapOptions = {
center: LatLng,
zoom: 20,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("dvMap"), mapOptions);
var marker = new google.maps.Marker({
position: LatLng,
map: map,
title: "<div style = 'height:60px;width:200px'><b>Your location:</b><br />Latitude: " + p.coords.latitude + "<br />Longitude: " + p.coords.longitude,
});
google.maps.event.addListener(marker, "click", function (e) {
var infoWindow = new google.maps.InfoWindow();
infoWindow.setContent(marker.title);
infoWindow.open(map, marker);
});
var hidPlace = '<%= inpPlace.ClientID %>';
var lblplace = $('#lblplace');
var google_maps_geocoder = new google.maps.Geocoder();
google_maps_geocoder.geocode(
{ 'latLng': LatLng },
function (results, status) {
if (status == google.maps.GeocoderStatus.OK && results[0]) {
lblplace.text(results[0].formatted_address);
}
}
);
});
} else {
alert('Location feature is not supported in this browser.');
}
});
</script>
<section class="content">
<script src="http://maps.google.com/maps/api/js?key=key"></script>
<label id="latitude" runat="server"></label>
<br />
<label id="longitude" runat="server"></label>
<br />
<div id="dvMap" style="width: 500px; height: 500px" runat="server" visible="false"></div>
<input id="inpHide" type="hidden" runat="server" />
<input id="locHide" type="hidden" runat="server" />
<label id="lblplace" runat="server"></label>
<input id="inpPlace" type="hidden" runat="server" />
<br />
</section>
后面的asp.net c＃代码我可以得到经度作为纬度和经度，但lblplace每次都返回null值。请支持我找到我做错的地方。
隐藏字段
var hidPlace = '<%= inpPlace.ClientID %>';
var lblplace ='<%= locHide.ClientID %>'
var google_maps_geocoder = new google.maps.Geocoder();
google_maps_geocoder.geocode(
{ 'latLng': LatLng },
function (results, status) {
if (status == google.maps.GeocoderStatus.OK && results[0]) {
document.getElementById(hidPlace).value=results[0].formatted_address;
}
}
);
